Definitions

  • Each screen frame is covered with a gauze with photoengraved perforations which exactly reproduce the portion or portions of one colour of the design and/or wording.
  • the screen is placed on the fabric and a printing paste of the desired colour is repeatedly spread over the gauze by means of one or more squeegee blades so that, opposite the engravings, the underlying fabric remains printed as a consequence of the extrusion of the printing paste through them.
  • the operation is repeated with all the screens prepared for the different colours composing the design and/or wording which, finally, remains impressed on the fabric.
  • Automatic machines for the screen printing of fabrics which comprise a conveyor belt which is caused to advance stepwise so as to bring each fabric piece or garment opposite the printing screens, which are supported one after the next above the conveyor belt.
  • the conveyor belt When the conveyor belt is stationary the screens are lowered onto their respective fabrics and the wheeled squeege blades are drawn to and fro so as to extrude the printing paste through the engravings on the gauze.
  • the aforesaid problem is readily solved by making marks or providing reference means on the conveyor belt, by means of which marks or reference means the fabric piece can be immediately centered with respect to the printing screen. Furthermore, the belt is normally self-adhesive in order to keep the fabric firm during the printing operations.
  • the solution is not as simple as this: for the prime condition for a perfect centering of the garment in the desired position with respect to the printing screen is that the garment be placed on the conveyor belt with its parts, i.e. front and back, in a very exact reciprocal position of symmetry. In this case, moreover, the self-adhesive belt cannot keep the whole garment firm in that it can act only on one part of it, that is to say the front or the back.
  • the object of the present invention is to solve the aforesaid technical problems connected with the processes of screen printing of fabrics, in particular of finished garments having a front and a back.
  • the present invention proposes an automatic apparatus for printing fabrics, in particular finished garments, of the type provided with a plurality of printing screens which can be lowered and raised with respect to garment support means, characterized by the fact that said garment support means comprise a plurality of forms mounted in a distanced manner on a conveyor means which is stepwise advanceable, so as to bring each form in succession opposite each printing screen.
  • FIGS. 1 and 2 are two vertical section views which respectively illustrate the two operational positions of an apparatus embodied according to the invention.
  • FIG. 3 is a plan view of the apparatus.
  • the apparatus in question consists structurally of a frame 10 preferably, but not necessarily, mounted to wheels 11.
  • the frame 10 comprises a base 12 from which extend a stationary central column 13 and a plurality of peripheral uprights 14.
  • each printing screen 16 comprises a removable gauze 17 run over by one or more squeegee blades 18 moved to-and-fro by a motor 19, through a chain transmission.
  • each printing screen 16 is connected, by a chain or similar means 20, to the free end of a stem 21 of a hydrodynamic cylinder 22.
  • the cylinder 22 extends solidly from the top of a shaft 23 axially rotatable within a shell 24 which is in turn rotatably mounted within the stationary tubular column 13.
  • the translation of the shaft 23 is controlled by a hydrodynamic cylinder 25 with causes a wedge-shaped cam 26 to act on an idle roller 27 at the lower end of the shaft 23.
  • the shell 24 is caused to rotate stepwise by a motor variator 28 through a speed reducer 29, an intermittent control 30, and a pair of gearwheels 31, 32.
  • the shell 24 controls the stepwise rotation of a carousel 33 consisting of a polygonal table 34, solid with the shell 24, on each side of which radially extend removable forms 35 into which the garment to be screen printed can be placed.
  • the machine When at rest, the machine has all the printing screens 16 in the wholly raised position as indicated with dashes and dots in FIG. 1. This position allows all servicing and/or repair of the machine, or the replacement of screens, to be carried out conveniently and with ample space.
  • the printing screens 16 are first lowered into the position of FIG. 2 by means of retraction of the stem 21, and then into the position of FIG. 1, by retraction of the wedge 26.
  • the printing screens 16 are raised to the position of FIG. 2 and the carousel is moved forward one step so as to bring each garment below the next, which is lowered for the printing of a different colour, and so on until completion of the printing on each fabric garment by means of the use of all the printing screens 16.
  • a stable operating position for each printing screen 16 is assured by a stanchion 36 which is fitted into a respective groove 37 in the shaft 23.
  • each finished fabric garment can be fitted onto the forms 35 in a perfectly centered position and in a stable condition, so that the printing on it is performed in the exact position desired.
